`com.apple.security.cs.allow-unsigned-executable-memory` entitlements. This will allow the utility process
to load unsigned libraries. Unless you specifically need this capability, it is best to leave this disabled.
Default is `false`.
* `disclaim` boolean (optional) _macOS_ - With this flag, the utility process will disclaim
responsibility for the child process. This causes the operating system to consider the child
process as a separate entity for purposes of security policies like Transparency, Consent, and
Control (TCC). When responsibility is disclaimed, the parent process will not be attributed
for any TCC requests initiated by the child process. This is useful when launching processes
that run third-party or otherwise untrusted code. Default is `false`.
* `respondToAuthRequestsFromMainProcess` boolean (optional) - With this flag, all HTTP 401 and 407 network
requests created via the [net module](net.md) will allow responding to them via the
[`app#login`](app.md#event-login) event in the main process instead of the default
